SPECIFICATION forming part of Letters Patent No. 604,209, dated May 1'7, 1898. Application filed November 3, 1897 Serial No. 657,257. (No model.)

T all whom it may concern.-

Be it known that I, HENRY F. GABEL, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Gas-Burners for Water-Heaters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a vertical section of a waterheater provided with my improved burners. Fig. 2 is an enlarged vertical section showing the construction of the pilot-light burner; and Fig. 3 is a top plan view, partly broken away, of the pilot-light burner.

My invention relates to the gas-burners employed with water-heaters, and is designed to prevent the puffing out of the pilot-light when the main burners are ignited, which action is liable to occur on account of the slight concussion occurring on the lighting of these burners. It is also designed to prevent an accidental blowing out of the pilot-light and cutting off of its gas-supply.

In the drawings, 2 represents the outer casing of a water-heater, composed, preferably, of coils 3 and having a water-supply pipe 4 and an exit-pipe 5 leading to the house system. In the pipe tis placed an automatic regulator 6,0f any desired constructiomwhich controls the flow of water through the pipe 4, as well as the supply of gas through the pipe '7. The pipe 7 leads to an annular gas-chamber 8, to which are coilnected main burners 9, of any desired construction. 10 is the pilotlight burner, which is connected by a branch pipe 11 to the gas-supply pipe at a point beyond the regulating gas-valve therein, so that a small quantity of gas will always flow through this branch pipe to the pilot-light burner. This pilot-light burner is also connected to the main gas-chamber 8, and in its connection is placed a downwardly-seating valve 12,consisting preferably, of aloose ball, as shown in Fig. 2. At the end of the branch pipe 11 is provided a hollow regulating-plug 13, having slotted sides and engaging suitable screw-threads within the connection, so that the amount of gas flowing through the branch pipe may be regulated. The pilotlight burner proper consists of a base-plate 14, which is preferably square or of other angular shape, having an annular series of holes 15 and ribs or wings 16 between the same. A cover-plate 17 is secured above the wings by a suitable screw 18, and the gas and air passing from the holes 15 will burn around the plate; The ribs or wings between the holes are designed-to prevent the blowing out of the flame, since evenif the flames from some of the holes are blown out the draft or current of 'air will not reach all the holes, and hence a portion of the flame will remain and reignite the mixture flowing from the other holes. The square or. angular shape of this burner also assists in this action, since I have discovered by experiment that when a round burner is used the air-current is liable to flow around the same and totally extinguish the flame.

The action of my device is as follows: When the gas is cut off from the main burners, a small current of gas will flow through pipe 11 to the pilot-light burner, this amount being regulated by the plug 13. When the gas is turned on to the main burners, the pressure in the reservoir 8 will lift the valve 12 and allow a larger supply of gas to pass the pilot-light burner, which then becomes one of the main heating-burners and is preferably of even greater capacity than such burners. Its accidental extinguishing by concussion on the lighting of the other burners is therefore avoided. When the gas is again cut off from the main burners, the ball-valve 12 will drop to its seat and the pilot-light will burn with a small flame, as before.

The automatic valve between the pilot-light burner and the supply reservoir or pipe is an essential element, since without it when the supply of gas to the main burners is cut off the gas flowing through the branch to the pilot-light would tend to be drawn back to the main burners and the pilot-light thus be extinguished.

The advantages of my invention result from the fact that a simple and effective construction is afforded by which the puffing out of the pilot-light upon the ignition of the main burners is prevented, while the accidental extinguishing of the pilot-light by drafts of air is prevented by the peculiar construction of this burner. There being no easily-accessible regulating-valve in the branch pipe 11, the pilot-light cannot be turned 01f, nor can the supply of gas thereto be increased, so as to give too large a flame.

Many variations in the form and arrangement of the pilot-light burner may be made w--without departing from my invention, since I 01am 1. The "combination with a water-heater having -a heating-bii'rnenpf a valved gassupply leading thereto, a pilot-light burner having a branch supply-pipe extendingtherefrom to the main gas-supply at a point beyond the valve therein, and another connection leading from the pilot-light burner to the main gas-supply between the valve therein and the heating-burner and provided with an automatic valve which prevents backfiow from the pilot-light burner to the heatingburner when the gas-supply to. the heatingburner is cut off.

2. The combination with a water-heater having aseries of heating-burners connected to a common supply-chamber extending beneath them, of a pilot-light burner also con nected to the common supply-chamber and vhaving a downwardly-closing gravity-valve in the connection, said valve being arranged to be lifted by the pressure of gas, and a branch supply-pipe leading to the pilot-light burner at a point between this burner and the gravity-valve.

3. A gas-burner of square or angular shape having a plate provided with jet-openings,

and outwardly-projecting separating wings or ribs between the openings.

4. An angular gas-burner havinga central portion provided with ribs or partitions ex- HENRY F. GABEL.
